IMPROVEMENT IN APPARATUS FOR TREATING 0R DRYING SCRAPS 0R OFFAL.

Specification forming part of Letters Patent No. 163,565, dated May25,1875; application filed April 16, 1875.

art to which it pertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

The nature of this invention consists in the construction andarrangement of an apparatus for treating or drying scraps or oii'al, aswill be hereinafter more fully set forth.

In the annexed drawing, Figure l is a longitudinal section of a deviceembodying my invention, and Fig. 2 is a transverse section taken on theline 00 m of Fig. l.

A represents a cylindrical tank of any suitable dimensions, made,preferably, double or jacketed, so as to retain the heat therein for alonger period, and provided with a suitable lid or door for theinsertion and removal of the material to be operated upon. lVithin thistank is a revolving cylinder, consisting of two hollow heads, B,connected by tubes or pipes O. The hollow heads B may be constructed oftwo or more arms, as shown, and connected by means of the horizontalpipes O 0, running from one head to the other, and placed at suitableregular intervals. The heads B B are provided with hollow journals a I),which pass through stuffing-boxes attached in the ends of the tank. Thejournal (0 is the inlet for the isteam or hot air, and the journal I) isthe out- The cylinder is revolved by means of suitable gearing appliedto one of the journals, thereby keeping the contents of the tank inconstant agitation. Steam or hot air is introduced through the hollowjournal 0 into the head B at that end; thence through the pipes G G intothe other head B, and out of the exhaustjournal b, during its passagewarming and drying the contents of the tank while disturbed.

On top of the tank A is secured an inverted funnel, D, opening into thesame, and its upper end opening into the center of a pipe, E, as shown.One end of this pipe is, by a pipe, G, connected with the exhaustjournalI), so as to conduct the exhaust-steam or hot air through the pipe E,past the communication with the interior of the tank, thereby creatingsuction to draw out the steam and moisture of the material being dried.

Having thus fully described this invention, what is claimed as new, anddesired to be socured by Letters Patent, is-

1. The combination of the tank A, hollow cylinder-heads B B, with hollowjournals ct I), and the pipes O 0, connecting said heads. and runningparallel with the axis of the cylinder, substantially as herein setforth.

2. The combination of the tank A,T-shaped pipe D E, and the pipe Gr,conducting the exhaust through the horizontal part E of the pipe,substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I aiiix my signaturein presence of two witnesses.
